all "111. out it may concern. Ba known that l, H. Scnnonrnn, a Ul-blZQllof the United States, and resident Chicago, county of Cook, and State of.5 Illinois, have nvented certain new and useful improvements inCandy-Making Machines, of which the following is a specifin, which areillustrated in the drawings, forming a part there n.

e invention. relates to apparatus for cooking and mixing such materialsas candy the like, and. more particularly to such apparatus wherein theheat for cooking the material is derived from a gas furnace.

The object of the invention is to provide cand}-' making apparatus whichshall be of improved construction and eilicient in oper ntion. iseLreinplified in the strucreinsater described and which d in theaccompanylng drawe u is a side elevation of a candy machine e1 ibodvingthe features of provided by the invention. s. u are detail plansectional views o the lines 3-3, respece apparatus are preferably 'tablestandard. In Figs wings, such a standard. in, ii). it rises from. afloor plate, floor plate also serves for supportfor receiving a furnacereferably the elevation at held by the furnace, is, is ado ustable.

po 'l of a pair of telescoping ac pted be held in relad position by aset screw, 17. "(as burner of the furnace, is, burner is conveniently ya flexible pipe,l9,'and pipe, 2i, which leads from a permit of thevertical le adj o the furnace, l lfl/ilii pipe, 21, is shown as having aflexible section, 22.

a blower fan, Q0, is shown as being hung un-r r side of a bracket, 23,which standard, 12,.adiacent its 2%, mounted on the o :cket, 23, servesfor 20, as through. a belt, =nt- As shown, the

ed upon the motor and the other upon the blower.

A kettle is used for containing the batch of material to be treated. InFigs. 1 and 2 of the drawings this kettle is shown at 28. It is normallysupported directly over the furnace,'1 l, the vertical adjustment of theurnace serving to accommodate kettles of different depth. Most desirablythe means for supporting the kettle is of such construction thatit maybe lifted from the furnace as when the cooking of the batch of materialhas been completed or. when the cooking is found to be proceeding toorapidly. As shown, the kettle, 28, has handles, 29 and 30,- at itsopposite sides and these handles rest upon the arms 31 and 32, respectively, of a bifurated bracket, The

bracket, 33, is slidingly mounted upon the 1 standard 12. To this endthe bracket shown as being provided with a beaiing which slidinglyincloses an intermed part, as 35, of the standard. reforably shouldersas 36 and 37 are provided for limiting the slidingmoveinent of thebracket, 33, in each direction, as by making the part 35 of the standardof reduced diameter.

A stirrer shaft, 38, extends down 'ardly into the kettle, 28, andpreferably has a dash er, 39, fixed upon its lower end. For supportingthe stirrer shaft, 38, in an up right position, it is journaled in abracket arm, 40, and in abearing, 11, the latter being formed upon theoverturned higher end of the, standard, 12. Pileferably the stirrershaft, 38, rotated by power derived froin the same motor, 24, which isused for driving the blower fan, 20. As shown, this poweristransmitted.through a counter shaf, 42, mounted at the top of thestandard,- 12, as by being ournaled in upstanding brackets, 4-4: andSpeed reducing gears, as all i7, i8 and d9 serve for operativelyconnecting the counter shaft, 42, with the motor, 24:. The gear, 46, ismounted upon the counter shaft, s2, and is normally connected therewithby a clutch indicated at The gears, 47, 48, are mounted upon anintermediate shaft, 50. T his shaft is convenmay journaled in thebracket, 45, below the counter shaft, 42. The gear, 49, is mount 2d uponthe motor, 24c, and meshes with the gear 5;. Beveled gears, 51 and servefor operatwely connecting the counter shaft, 4.2, and s rer shaft, 38.The clutch, i3,

per-

mits the blower fan, 20, to be operated independently of the stirrershaft, 38, as when a fresh batch of material is to be softened in thekettle, '28, by heat from the furnace, 14, prior to being stirredby thedasher, 39.

To permit the kettle, 2 8, to be lifted from the furnace, 14, Withoutinterrupting the operation of stirringflthe material contained in thekettle, the stirrer shaft, 38, is slidingly mounted in the bearing, 41,-and beveled gear, 52. As shown, the beveled gear, 52, is connected withthe stirrer shaft, 38, by a spline, 53. The bracket 40 serves forraising the stirrer shaft, 38, Whenever the kettle, 28, is lifted. Tothis end the bracket, 40, is formed integral with the bracket, :33. To

provide an additional support for thebracket, 40, said bracket ispreferably made in the form of an elbow and a T (Fig. 3) is provided atthe angle of the elbow for running in a slideway, 54, formed on thestandard, 12. A collar, 56, fixed, upon the stirrer shaft, 38, above thebracket, 4.0, prevents downward movement of the shaft through thebracket and insures the shaft being elevated with the bracket.

Any convenienthand operated mechanism may be employed for'raising andlowering" the bracket, In the form of construction illustrated on sheet1, a screw. 57, turned by beveled gears, 58, 59, and a lever or crank,60, is employed. Thescrew, 57, is shown as belng journaled adjacent itsopposite ends in bracket lugs, 61, 62, formed upon the 'side of thestandard, 12. This. screw passes through and has threaded engagementwith a lug, 63, formed on the bracket. 33. The beveled gear, 58, isfixed uponthe higher end of the screw, 57. The beveled gear, 59, and thecrank, 60, are preferably rigidly connected and are rotatably mountedupon a stud, (34, mounted upon the side of the standard, 12, adjacentthe higher end of the screw.

In the operation of the apparatus. the motor, as 24, is employed fordriving the blower fan, 20, but without driving the stirrer shaft, 38,until the batch of material contained in the kettle '28, has beensufficiently softened by the heat from the fnrmice, 14, to permit ofthemovement of the dasher,

On closing the clutch, 43, the

motor, 24:, serves to drive both the blower fan, 20 and the dasher, .39.lVhen the batch of material has been sufiiciently cooked, or

in event the cooking is found to proceed too 33, and kettle 28, in anyof its adjusted position s. In this form of. construction, the

kettle may be raised and lowered Without interrupting, the mixingoperation.

I claim as my mvent1on- 1. In a candy-making machine, in combination, akettle, a stirrer shaft extending into the kettle, a driving gear fixed.against 'translatory movement .splined upon the stirrer shaft, :1wertically movable supporting arm connected to the kettle and to thestirrer shaft and a vertically disposed screw fixed against longitudinalmovement and having threaded engagement withthe said supporting screw. ac

' 2. In a candy making machine, in combination, a standard. a kettle,a-bracket movably connected to the standard and supporting the kettle, avertimilly'movable upright stirrer shaft having its lower end-extendedarm and means for turning the into the kettle,.a pair-of separatedjournaled bearings for the stirrer shaft, one-being fixed to thestandard and slidingly receiving the shaft adjacent its-upper end andthe other journal bearing beingcarr iedby the movable bracket andslidingly receiving the shaft'intermediate its ends means limiting k thesliding of the shaft through thela'st'mem u means for raising andlowering the bracket.
